Claims.

This invention relates to the manufacture of shoes and is illustrated as embodied in a heelseat-itting machine having a support comprising an expansible form for positioning in the machine the heel ends oi shoes oi the last and the shoes against movement after they have been positioned in the machine.

ln United States Letters Patent No. 1,902,824, granted March 28, 1933 on an application led in my name there is disclosed a heel-seat-tting and left shoes upon lasts may be eectively centered and clamped against movement in the machine by mechanism including arms which respectively engage the opposite sides of the counter portion of the outside of the shoe with a substantial amount of pressure. ln order further to insure that the shoe is held securely in the above machine during the heelseat-ntting operation the overlasted counter the last is forced by such mechanism against rand crease entering plates the of the machine.

lt is an object of the present invention to provide an improved machine which will operate upon shoes off the last to ht their heel seats for the reception of wood heels, With this in view I have provided a form well adapted for use in the machine of the above-identied application, which will effectively support the marginal parts of the heel seat of the inside of the shoe as the overlasted counter portion of the shoe is forced against the crease plates and which will also support the sides of the counter portion of the shoe against distortion under pressure of the centralizing and clamping arms. In order to expedite heel-seat-litting of shoes ofi the last, the form should be, and as illustrated is, oi such shape that the operator can readily mount the shoe upon the form and remove the same therefrom at the beginning and the end respectively, of such operation. Furthermore, the illustrated form automatically co-operates with other parts of the machine to position and to clamp the shoe in the machine without the operator having to perform any operations not required when tting the heel seats of shoes on the last.

While the illustrated expansible form is described with reference to the above-mentioned machine, it will be understood that such form may be used for supporting and positioning shoes on? the last in various other types of machines.

lt is a further object of the present invention to provide, in a machine for operating upon the heel ends of shoes, an expansible form which will .automatically and ei'ectively support and centralise a shoe off the last as the shoe is clamped in a heel-seat-tting or other machine.

With the above objects in view and in accordance with a feature of the present invention, the illustrated machine is provided with an expansible support 'or form shaped for reception within the heel end oi a shoe and with mechanism to force the support toward a plate which is shaped and arranged to engage the rand crease of the shoe, the support being constructed for expansion to force the same into engagement with the counter portion of the inside oi the shoe as the shoe is forced against the plate by such mechanism. Preferably such engagement occurs over a relatively large area to insure a hrm support for the shoe in the machine.

The illustrated expansible support comprises a pair of forms which are pivotally mounted for movement toward and away from each other upon a plunger. The plunger is yieldingly supported upon a block that may be readily mounted in operative position upon a jack post of the abovementioned machine in place of a last pin block, when it is desirable to change from on-the-last to o-the-last work. The block is provided at 8.0 its upper end with a pair of wedge faces against which the respective forms are held by a spring carried by the forms. When a shoe mounted upon the forms and having its overlasted counter portion in engagement with rand crease entering plates of the machine is positioned in the machine, the jack post is raised to force the shoe against the plates. Upward movement of the jack post causes the wedge faces to force the forms into engagement with the counter portion of the inside of the shoe, prior to exerting a clamping pressure against the outside counter portion of the shoe by centralizing and clamping arms, and thereby preventing the counter portion from being distorted by such arms. As the jack post is raised the top faces of the forms, which engage a substantial portion of the heel seat of the inside of the shoe, eiectively support the heel seat and cooperate with the crease plates to clamp the shoe in the machine.

Fig. 1 shows a longitudinal vertical section of a portion of the heel-seat-tting machine .disclosed in the above-mentioned United States Letters Patent No. 1,902,824 and also shows in side elevation the illustrated expansible form and mechanism for operating the same incorporated in such machine;

Fig. 2 is a plan view of the portion of the machine illustrated in Fig. 1;

machine taken constructed and arranged to replace a last pm block (not shown) which is poack post 22 when the machine is operating upon shoes on the last.

The block 24 is constructed to receive a head 25 (Fig. l) comprising the expansible form 20 which consists of a pair of pivotally adjustable angular forms 20a, 20h, shaped and arranged to engage the heel and the counter portions 26 and 28 of the insides of shoes of different sizes and styles.

The jack post 22, if desirable, may be formed integrally with the block 24 and is bored to receive a cylindrical rod 30 (Fig. l) which supports the jack post through a spring 32, the upper end of which engages a shoulder 34 of the rod 30. In order to swing the jack post 22 from loading or forward position shown in dotted lines in Fig. 1, to an upright As jack post 22 rearwardly of the machine he grasps the shoe and depresses the same slightly against the pressure of the spring 32 so as to bring the rand crease of the shoe into engagement with a frame about a vertical axis passing through point 44 (Fig. 2). The spring 32 is of suficient strength to force the shoe with a slight amount of pressure against the underside of crease plates 42 vicinity of its breast line. Such movement is effected by providing the V-shaped gage 46 with a pin 54 which is movable along a slot 56 formed in one of the arms 50. When the arms 50 are in engagement with the shoe, the V-shaped` gage 46, together with the arms 50 are movedl rearwardly upon the slide 48 until the rear end4 ofv the counter portion of the shoe engages they back gage 38 to position the shoe lengthwise in the machine.

After the shoe has been positioned in4 the maiare moved further into shoe in order to serve as sole while it is being operated chine the crease plates 42 the rand crease of the supports for the In order further to insure that the shoe is clamped against movement while being operated upon, the above-identified machine is constructed and arranged to plates are being moved toward the illustrated construction this each other. In

der operate yieldingly.

The relative strengths of the springs 66 and 68 are such that upon downward movement of the prior to the time that the arms 50are forced by the crease plates 42 against the outside of the counter portion of the shoe. The hand lever 60 is moved downwardly until the pressures exerted against the inside and the outside counter portions of the shoe are approximately equal. During the downward movement of the hand lever 60 and until the shoe is nally clamped, the pressure exerted against the inside counter portion of the shoe by the forms 20a, 20h is slightly in excess of the pressure exerted against the outside of the counter portion by the arms 50. This diierence of pressure, however, is not suicient to distort the counter portion of the shoe and insures that the arms will not crush in the counter portion of the shoe as it is positioned and clamped in the machine. By providing the above arrangement shoes of dir"- ferent sizes and styles which are o the last may be effectively positioned and clamped in the above machine.

The block 24 and the head 25 which comprises the forms 20a, 20h and a plunger '76 through which such forms are supported upon the block 24 will now be described in detail. The block 24 is provided with a circular recess or guideway 72 of suitable size to receive a stem of the plunger 76, one side of the stem being provided with a slot '18 shaped to receive a pin 80 carried by the block. The pin 80 permits relative movement of the block 24 and the plunger 76 and also limits the extent of such movement under pressure of a spring 82 which is positioned within the circular recess '72. The top portion of the block 24 is bifurcated for the reception of a lower ange portion 84 of the plunger 76, which portion prevents the plunger from turning with respect to the block 24. rYhe plunger 76 is constructed and arranged to support the forms 20a, 20h which, when expanded against the counter portion of the shoe substantially fill up the entire heel end of the shoe. The forms 20a, 2017 are pivotally mounted at their rear ends upon a pin 86 which is in threaded relation with the lower ange portion 84 of the plunger 76. The upper surface 88 of the lower flange portion 84 serves as a support for the forms 20a, 20h as the same are moved toward and away from each other about the pin 86 through mechanism which will be described later. The plunger '76 is also provided with an upper flange portion 90 having a circular shape and arranged for reception within opposed slots 92 of the forms 20a, 20h. The iiange portion 90 assists the lower ange portion 84 in supporting the forms 20d, 20h and also insures that during the operation of the machine such forms cannot be accidentally lifted off the pin 86.

1n order to expand the form 20 each of the iorms 20a, 20h is provided with a depending portion 94 constructed and arranged to engage a corresponding beveled face or wedge portion 96 of the upper end of the block 24. The plunger '76 and the forms 20a, 20h, are normally held in a raised position relatively tc the block by the spring 82, the arrangement being such that the forms 20a, 20h when in a raised position contact with the upper ends of the wedge portions 96, respectively. The forms 20a, 20h are normally held together to assume a closed position when the plunger '76v is raised with respect to the block 24, by a torsion spring 98, which is included in recesses 100 of the forms and has its central portion coiled about the pin 86 and its opposite ends inserted in recesses 99 formed in the respective forms.

As the jack post 22 is raised by the cam 62 to force the. overlasted: counter portion ofV the shoe against the crease plates 42, the jack post and the block. are raised to cause the wedge portion 96 to engage the respective depending portions 94, thereby expanding the form 20 against the inside counter portion of the shoe. When the sole has been trimmed the hand lever is raised to swing the cam 62 forwardly out of contact with the roll 64 and to move the arms 50 away from the counter portion of the shoe. When the cam 62 has been moved out of contact with the rolls 64 the spring 82 which is stronger than the spring 32, depresses the block 24 relatively to the forms 20a, 20h and permits the torsion spring 98 to move the forms 20a, 20hv toward each other. The jack post 22 is then swung to its loading position (Fig. 1) to remove the shoe from the machine. It will be noted that in operating upon shoes on the last the last pin block of the machine is slidingly supported for movement along an undercut guideway 102 of the jack post 22 in order to permit the last pin block to shift from side to side to accommodate right and left lasts, the last thimbles of which are not centralized with respect to the median plane of the heel-seat portion of the last. When operating upon shoes off the last, however, the block 24 may be initially centralized along the guideway 102 of the jack post 22, after which it is clamped in such position by turning screws 104 carried by the block and having their respective inner ends in engagement with a yieldable portion 106 (Fig. 4) of the block.

Forms of different sizes and shapes may be positioned upon the plunger 76 if desirable according to the sizes and styles of shoes being operated upon. The top faces 108 of the forms 20d, 2017 should support as much as possible of the heel end of the shoe in order that such faces will cooperate effectively with the crease plates 42 in clamping the heel portion ofl the shoe against such plates.

The opposite sides of the counter portion of the inside of the shoe are positioned at substantially equal distances from a median plane 110 of the heel-seat portion of the sole and forms which are symmetrical may be used to centralize the shoe without the use of arms 50. Although the opposite portions of the inside of the shoe are of slightly different shapes, it has been found that if the side faces 112 (Fig. 1) of the forms 20a, 20D are approximately of the mean shape of the opposite sides of the counter portions, the forms will operate effectively to support the shoe against distortion and to centralize the same. It

has been found preferable, however, initially to l centralize a shoe in the illustrated machine by the use of arms 50 before the shoe is forced against the crease plates, thereby positioning the shoe with a minimum amount of effort.

Although the above-described form 20'has been illustrated with reference to the heel-seat-fitting machine described in 'United States Letters Patent No. 1,902,824 it will be clear that the form may be advantageously used in various other types of machines.
